The energy and core structure of the c-edge basal dislocation in wurtzite GaN were modelled within the framework of empirical potentials (modified Stillinger-Weber). In addition to the core configurations already known, 2 new ones without wrong bonds were reported. The calculations showed that the configurations which contained wrong bonds were the most energetically favored in both glide and shuffle sets.
